It was all over at 2 am. It means our answer will include Imaginary Numbers. In some ways it is easier: Hide Ads About Ads. Quadratic Equations An example of a Quadratic Equation: Quadratic Equations make nice curves, like this one: Name The name Quadratic comes from "quad" meaning square, because the variable gets squared like x 2. This one is not a quadratic equation: The " solutions " to the Quadratic Equation are where it is equal to zero. They are also called " roots ", or sometimes " zeros ".
We can Factor the Quadratic find what to multiply to make the Quadratic Equation. Or we can use the special Quadratic Formula: C The method of completing the square can be used to solve every quadratic equation. D The quadratic formula can be used to solve every quadratic equation 2.
Fill in the blank with one of the words or phrases listed below. A completing the square B discriminant C quadratic D quadratic formula 3. A A quadratic equation in this form can always be solved by factoring. B The left-hand side of this equation is called a difference of two squares. C A quadratic equation in this form can always be solved using the square root property.
Which of the following statements best describes how to derive the quadratic formula? D The quadratic formula can only be derived by using calculus.
Are you sure you want to delete this answer? To factor these equations you have to guess at the factors and see if they work. If not use the quadratic formula.
